將SAML2 AuthnRequest轉換爲Java類

Question

我使用OpenSAML 2.6.5作爲SAML2庫。 我還沒有找到有關如何編組表示來自服務提供者的AuthnRequest的字符串（XML文檔）的文檔。 任何人都可以幫助我嗎？

Answer 1

讀取來自SP的要求，你需要編碼解組輸入字符串，像這樣：

DefaultBootstrap.bootstrap(); //crucial in SAML2 
    byte[] decodedSamlAsBytes = Base64.decode(incomingEncodedSaml); 

    DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder docBuilder = documentBuilderFactory.newDocumentBuilder(); 

    Document document = docBuilder.parse(new ByteArrayInputStream(decodedSamlAsBytes)); 
    Element element = document.getDocumentElement(); 

    UnmarshallerFactory unmarshallerFactory = Configuration.getUnmarshallerFactory(); 
    Unmarshaller unmarshaller = unmarshallerFactory.getUnmarshaller(element); 
    XMLObject requestXmlObj = unmarshaller.unmarshall(element); 
    AuthnRequest request = (AuthnRequest) requestXmlObj;
